> If you say ACCEPT 62, do you accept any combination of nested content types?

Yes. A CoAP request can include at most one Accept option and any
response must exactly that value as Content-Format or be an error
response. CoAP doesn't have a mechanism for negotiating the content
formats of representations embedded in other representations. I
stumbled upon the same problem with CoRAL.

> Should something about this be placed into the draft?

Yes. Proposed text: "CoAP doesn't have a mechanism for negotiating the
content formats of representations embedded in
application/multipart-core representations."

> Also I note that this draft is currently expired and needs to be reposted.

Yes. Soon™.
